Hittokapu Bay

Hittokapu Bay (147.63E
44.93N), also known as Tankan Bay, is located on the island
of Etorofu in the southern Kuriles.
It was
the assembly point for the Pearl
Harborstrike
force, chosen for its isolation, but it played little further role
in
the war. Facilities were limited to a couple of small concrete wharfs;
the Pearl
Harbor
strike force had to bring oilers
to the bay to top off
from before sailing.

By August 1945, Etorofu and the nearby islands were defended by 89 Division. However, these offered no resistance to the three Russian naval infantry battalions that landed on 28 August, 13 days after the Japanesesurrender.
